Molecular Evolution of the Primate Antiviral Restriction Factor Tetherin
30 Jul 2010
Abstract excerpt
BACKGROUND: Tetherin is a recently identified antiviral restriction factor that restricts HIV-1 particle release in the absence of the HIV-1 viral protein U (Vpu). It is reminiscent of APOBEC3G and TRIM5a that also antagonize HIV.
